Abstract
Extrusion coating of electrode plates for lead-acid electrochemical cells is enhanced by mixing an ionic water soluble organic dispersant in to the aqueous-based lead paste.
Claims6
A method for preparing an electrode plate for a lead-acid electrochemical cell, comprising the steps of:
- (a) mixing an electrochemically active lead material, an aqueous-based vehicle and an ionic water soluble organic dispersant to form an extrudable paste slurry;
- (b) providing a substrate;
- and
- (c) extrusion coating said paste slurry on to said substrate.
